Abstract
A precharging circuit for precharging an intermediate circuit capacitor of a converter formed from at least one electrolytic capacitor using a grid current from a supply grid before the converter is connected to the supply grid and is used for the reformation of at least one electrolytic capacitor of the intermediate circuit capacitor. A method is provided for the reformation of an intermediate circuit capacitor of a converter formed from at least one electrolytic capacitor, which is connected to the supply grid using a precharging circuit. A converter is created for converting an AC grid voltage into a direct voltage or vice versa, with a device for the reformation of electrolytic capacitors of an intermediate circuit capacitor of the converter using an integrated precharging circuit of the converter. Existing hardware can be used for the reformation of electrolytic capacitors in a converter, and the expense associated with the reformation can be minimized.
